From February 1943 flush riveting was used on the fuselage, affecting all Spitfire variants. LA201's poor flight control qualities during trials in late 1944 and early 1945, led to a damning report from the Air Fighting Development Unit, must be emphasised that although the Spitfire 21 is not a dangerous aircraft to fly, pilots must be warned ... in its present state it is not likely to prove a satisfactory fighter. In 1942, the United States acquired a flyable, Japanese, This aircraft survived the war, only to be scrapped in 1945. [37] After the war, second hand Mk XIVs were exported to a number of foreign air forces; 132 went to the Royal Belgian Air Force, 70 went to the Royal Indian Air Force and 30 of its reconnaissance variant went to the Royal Thai Air Force. [28], The British public first saw the Spitfire at the RAF Hendon air display on Saturday 27 June 1936. On reflection the general scheme became clear. All went according to plan until, when we were about halfway between Odiham and Farnborough and going flat out, I was beginning to overhaul the Fw 190 and the Typhoon. [56] Behind the bulkhead were five U-shaped half-frames which accommodated the fuel tanks and cockpit. [64] A dihedral of 6° was adopted to give increased lateral stability. Both were shot down and became prisoners of war, while flying Spitfires over France in 1941 and 1942. [37] Beaverbrook immediately sent in experienced management staff and workers from Supermarine, and gave control of the factory to Vickers-Armstrong. To avoid the expansion of fuel in hot weather damaging the wing, pressure relief valves, incorporating small external vent pipes, were fitted near the wing tips.[5]. From 1948 onwards, Arabic numerals were used exclusively. [94], Due to a shortage of Brownings, which had been selected as the new standard rifle calibre machine gun for the RAF in 1934, early Spitfires were fitted with only four guns, with the other four fitted later. "[117] Although not as fast as the Spitfire, the Zero could out-turn the Spitfire with ease, could sustain a climb at a very steep angle, and could stay in the air for three times as long. This wing was tested on a modified F Mk 21, also called the F Mk 23, (sometimes referred to as "Valiant" rather than "Spitfire"). Mitchell has sometimes been accused of copying the wing shape of the Heinkel He 70, which first flew in 1932, but as Beverley Shenstone, the aerodynamicist on Mitchell's team, explained: "Our wing was much thinner and had quite a different section to that of the Heinkel. The "fishtail" design of ejector exhaust stub gave way to ones of circular section. The first four frames supported the glycol header tank and engine cowlings. V. It is finished in its original presentation markings. The Spitfire was to be a sort of datum pacemaker – 'Mr Average Contemporary Fighter' – and its job would be to come in last, the real excitement of the proceedings being by how much it would be beaten by the Fw 190 and the Typhoon, and which of these two bright stars would beat the other and by how much. "The Early Griffon Spitfires part 1: Article and scale drawings", Cooke, Peter. Air International (article). A new five bladed Rotol propeller of 10 ft 5 in (3.18 m) in diameter was used, although one prototype JF321 was fitted with a six bladed contra rotating unit. Media related to Supermarine Spitfire Mark XIV at Wikimedia Commons. [124], During the Second World War, Spitfires were used by the United States Army Air Forces in the 4th Fighter Group until they were replaced by Republic P-47 Thunderbolts in March 1943. Their Supermarine Aircraft Spitfire is supplied in kit form and is the only all-aluminium reproduction Spitfire in production. [39] Different wings, featuring a variety of weapons, were fitted to most marks; the A wing used eight .303 in (7.7 mm) machine guns, the B wing had four .303 in (7.7 mm) machine guns and two 20 mm (.79 in) Hispano cannon, and the C, or universal, wing could mount either four 20 mm (.79 in) cannon or two 20 mm (.79 in) and four .303 in (7.7 mm) machine guns. Later, other squadrons in the Far East and Middle East would receive them. And it looked nice. [105], Well-known Spitfire pilots included "Johnnie" Johnson—34 enemy aircraft (e/a) shot down[106]—who flew the Spitfire right through his operational career from late 1940 to 1945. During the Battle of Britain, from July to October 1940, the public perceived the Spitfire to be the main RAF fighter, though the more numerous Hurricane shouldered a greater proportion of the burden against Nazi Germany's air force, the Luftwaffe. [42] The Mk 21 armament was standardised as four 20mm Hispano II cannon with 150 rpg and no machine guns. I realised at once that we should have to correct its directional characteristics and probably its longitudinal stability also, both of which in due time we achieved. V airframe, it was not only longer, but its thrust line had to be angled down a little. One feature of the Griffon engine which was to catch a lot of pilots out was that the propeller rotated in the opposite direction to that of the Merlin; i.e.,: to the left, from the pilot's perspective, rather than to the right. [30], As a result of the delays in getting the Spitfire into full production, the Air Ministry put forward a plan that its production be stopped after the initial order for 310, after which Supermarine would build Bristol Beaufighters. The Supermarine Spitfire is a British single-seat fighter aircraft that was used by the Royal Air Force and other Allied countries before, during, and after World War II. The Merlin 46 and Merlin 50 were also used in the VB. On 7 March 1942, 15 Mk Vs carrying 90-gallon fuel tanks under their bellies took off from HMS Eagle off the coast of Algeria on a 600-mile (970 km) flight to Malta. The Griffon engine drove an 11 ft (3.4 m)-diameter five-bladed propeller, some 7 in (18 cm) larger than that fitted to the Mk XIV. [4][nb 13] The Spitfire achieved legendary status during the Battle of Britain, a reputation aided by the "Spitfire Fund" organised and run by Lord Beaverbrook, the Minister of Aircraft Production. An experimental factory at Newbury was the subject of a Luftwaffe daylight raid, but the bombs missed their target and hit a nearby school. At the end of the trials, RAF pilots found that Firestreak infra-red guided missiles had trouble acquiring the Spitfire due to a low exhaust temperature, and decided that the twin ADEN 30 mm (1.2 in) cannons were the only weapons suited to the task, which was complicated by the tight turning circle of the Spitfire, and the Lightning's proclivity for over-running the Spitfire. The Spitfire IIB was a modification of the Spitfire I with a more powerful engine and factory-installed armour plate. [149] With these aircraft, 80 Squadron continued its patrol and reconnaissance duties from Wunstorf in Germany as part of the occupation forces, until it relocated to Kai Tak Airport, Hong Kong in July 1949. [98] If one cannon seized, the recoil of the other threw the aircraft off aim. The final Spitfire variant, the Mk 24, was similar to the Mk 22 except that it had an increased fuel capacity over its predecessors, with two fuel tanks of 33 gal (150 l) each installed in the rear fuselage. [81] Only two positions were available; fully up or fully down (85°). "Supermarine unveils its high-performance monoplane today (5 March). The cannon suffered frequent stoppages, mostly because the guns were mounted on their sides to fit as much of the magazine as possible within the wing. In total, 957 Mk XIVs were built, over 430 of which were FR Mk XIVs. ", "The Supermarine Spitfire, an operational history. The rear fuselage started at the 11th frame, to which the pilot's seat and (later) armour plating were attached, and ended at the 19th, which was mounted at a slight forward angle just forward of the fin. [47], The Mk 22 was used by only one regular RAF unit, 73 Squadron[48] based on Malta. Many of Supermarine's records from this era were destroyed during a bombing raid in 1940, and none of the surviving documents seemed to pin this down. The Merlin Mark I, the first iteration of the engine, produced a little more than 1000 horsepower. [114] Those Spitfire Vs were the first to see service outside Britain.[115].

The first deliveries of the Spitfire Mk VB variant took place at the start of 1943, with the first batch of 35 aircraft delivered via sea to the city of Basra, Iraq. Several other manufacturers have produced replica Spitfires, either as complete aircraft or as kits for self-building. A fibreglass replica of the Mk.1 Spitfire Mk1 YT-J (R6675), flown by Supermarine test pilot Jeffrey Quill during his brief period of active service with 65 Squadron, is on display at the. [154] The first airframe (PM631) developed mechanical issues which removed it from the trial. One Spitfire is kept in airworthy condition in the Israeli Air Force Museum. All this meant that the throttle needed to be handled judiciously on take-off but, once in the air, the aeroplane had a great feeling of power about it; it seemed to be the airborne equivalent of a very powerful sports car and was great fun to fly. The Spitfire continues to be popular among enthusiasts; nearly 60 remain airworthy, and many more are static exhibits in aviation museums throughout the world. Although full-scale production was supposed to begin immediately, numerous problems could not be overcome for some time, and the first production Spitfire, K9787, did not roll off the Woolston, Southampton assembly line until mid-1938.[1]. Many variants of the Spitfire were built, using several wing configurations, and it was produced in greater numbers than any other British aircraft. [32], In 1935, the Air Ministry approached Morris Motors Limited to ask how quickly their Cowley plant could be turned to aircraft production. Air combat was also felt to take place at relatively low speeds and high-speed manoeuvring would be physically impossible. A four blade Rotol propeller of 10 ft 5 in (3.1 m) was used. "Supermarine Spitfire (Merlin-engined variants)". [nb 10] Designers and pilots felt that having ailerons which required a degree of effort to move at high speed would avoid unintended aileron reversal, throwing the aircraft around and potentially pulling the wings off. [31] Mk XIVs with "tear-drop" canopies had 64 gal. 20,351 Spitfires were built in total. [75][76] During the Battle of Britain, pilots found the Spitfire's ailerons were far too heavy at high speeds, severely restricting lateral manoeuvres such as rolls and high-speed turns, which were still a feature of air-to-air combat. [46], Media related to Supermarine Spitfire Mark 22 at Wikimedia Commons, The Mk 22 was identical to the Mk 21 in all respects except for the cut-back rear fuselage, with the tear-drop canopy, and a more powerful 24 volt electrical system in place of the 12 volt system of all earlier Spitfires. The same engine was employed by the 100 Spitfire VI (Type 350) fighters built by Supermarine the first two of these AB176 and X4942 serving as prototypes. [42] The drawing office in which all Spitfire designs were drafted was relocated to Hursley Park, near Southampton. The wheels were occasionally fitted with disc-style covers. They were quite unqualified to make such a judgement and later events would prove them totally wrong.[43]. [2] As the Spitfire was no longer to be used as a night fighter, the retractable landing lights were no longer fitted. However, constant problems with the development of the Griffon meant that the decision to proceed with building a Spitfire with this engine didn't come to fruition until 1942, with the successful flight trials of the Mk IV.[12]. Fighter/ Fighter reconnaissance/ Photo reconnaissance. This website is devoted to the Supermarine Spitfire Type 300 prototype - serial number K5054 - and the production aircraft that followed her. Due to the high altitudes necessary for these dives, a fully feathering Rotol propeller was fitted to prevent overspeeding. It was concluded that the most effective and safest way for a modern jet-engined fighter to attack a piston-engined fighter was to engage full afterburner at an altitude lower than the Spitfire, and circle behind it to perform a hit-and-run attack, contrary to all established fighter-on-fighter doctrine at that time. Supermarine were seriously concerned because Castle Bromwich had been converted to produce Mk 21s and more were coming off the production lines daily. That Southeast Asia was a lower-priority area also did not help, and it was allocated few Spitfires and other modern fighters compared to Europe, which allowed the Japanese to easily achieve air superiority by 1942. [26] A week later, on 3 June 1936, the Air Ministry placed an order for 310 Spitfires,[27] before the A&AEE had issued any formal report. However the new wing gave less than perfect handling characteristics and so the Mk 23 was never built from the Mk 22 airframe as intended. They were extended by eight inches, meaning that with a straighter trailing edge, the wings were not the same elliptical shape as previous Spitfires. ", Jane, Fred T. "The Supermarine Spitfire. The last Lend-Lease shipment carrying the Mk IX arrived at the port of Severodvinsk on 12 June 1945. The elliptical wing was decided upon quite early on.

Each of these nine frames was oval, reducing in size towards the tail, and incorporated several lightening holes to reduce their weight as much as possible without weakening them. A fibreglass replica in the colours of a Polish squadron leader based at the station during the Second World War is on display at, A replica Spitfire is on display on the Thornaby Road roundabout near the school named after Sir Douglas Bader who flew a Spitfire in the Second World War. Private aircraft flew the first Merlin in 1933, but production for the Royal Army started in 1936. Its handling qualities have benefitted (sic) to a corresponding extent and it is now considered suitable both for instrument flying and low flying. The same day P7666 was delivered to the Squadron, 23 November 1940, Finlay destroyed a Bf 109 on his first operational sortie in the aircraft. I was also easily leaving the Typhoon behind and the eventual finishing order was, first the Spitfire, second the Typhoon, third the Fw 190. Like the Mk XIV there were fighter and fighter reconnaissance variants built. ", Lednicer, David A. [100], Even if the eight Brownings worked perfectly, pilots soon discovered that they were not sufficient to destroy larger aircraft. The trailing edge of the wing twisted slightly upward along its span, the angle of incidence decreasing from +2° at its root to -½° at its tip. [8], The Type 224 was a big disappointment to Mitchell and his design team, who immediately embarked on a series of "cleaned-up" designs, using their experience with the Schneider Trophy seaplanes as a starting point. The Seafire was a carrier-based adaptation of the Spitfire that served in the Fleet Air Arm from 1942 through to the mid-1950s. The managements of Supermarine and Vickers were able to convince the Air Ministry that production problems could be overcome, and a further order was placed for 200 Spitfires on 24 March 1938. The mark numbers XV and XVII (15 and 17) were reserved for the naval version, the Seafire, in an effort to reconcile the Spitfire numbering scheme with that of the Seafire. Wing Commander Peter Brothers, O/C Culmhead Wing in 1944–1945 and a Battle of Britain veteran; It was truly an impressive machine, being able to climb almost vertically – it gave many Luftwaffe pilots the shock of their lives when, having thought they had bounced you from a superior height, they were astonished to find the Mk XIV climbing up to tackle them head-on, throttle wide open! [19] After the fourth flight, a new engine was fitted, and Summers left the test flying to his assistants, Jeffrey Quill and George Pickering. [48][49], When the last Spitfire rolled out in February 1948,[50] a total of 20,351 examples of all variants had been built, including two-seat trainers, with some Spitfires remaining in service well into the 1950s. The Hispanos were found to be so unreliable that the squadron requested an exchange of its aircraft with the older Browning-armed aircraft of an operational training unit. In any case, it would have been simply asking for trouble to have copied a wing shape from an aircraft designed for an entirely different purpose. ... and this was transmitted to the rear propeller (which was rotating in the opposite direction) through the transitional bearing mechanism. [143], The Seafire II was able to outperform the A6M5 Zero at low altitudes when the two types were tested against each other during wartime mock combat exercises. This, though not ideal, produced a very marked improvement in directional characteristics and we were able to introduce minor changes thereafter and by various degrees of trimmer tab and balance tab to reach an acceptable degree of directional stability and control. The 224 was an open-cockpit monoplane with bulky gull-wings and a large, fixed, spatted undercarriage powered by the 600-horsepower (450 kW), evaporatively cooled Rolls-Royce Goshawk engine. These field-converted aircraft were allocated to 430 squadron RCAF. [4], The Hispano Mk.II cannons were now belt fed from box magazines allowing for 120 rpg (the "Chattellerault" system). … [31] The final cost of the first 310 aircraft, after delays and increased programme costs, came to £1,870,242 or £1,533 more per aircraft than originally estimated. These figures were only true to the first prototypes, as serial production examples were fitted with a Griffon 65 with different supercharger gearing. [147], As American fighters took over the long-range escorting of United States Army Air Forces (USAAF) daylight bombing raids, the Griffon-engined Spitfires progressively took up the tactical air superiority role, and played a major role in intercepting V-1 flying bombs, while the Merlin-engined variants (mainly the Mk IX and the Packard-engined Mk XVI) were adapted to the fighter-bomber role. "Spitfire con Coccarde Italiane (Spitfire in Italian service)." The resulting aircraft provided a substantial performance increase over the Mk IX. Supermarine Spitfire Mk. In late 1943 Spitfires powered by Rolls-Royce Griffon engines developing as much as 2,050 horsepower began entering service. A total of 1,185 aircraft of this model were delivered through Iran, Iraq and the Arctic to northern Soviet ports. In operational service many pilots initially found that the new fighter could be difficult to handle, particularly if they were used to earlier Spitfire marks.
